There are four main types of blood donors:
Autologous donors give blood so that it may be
transfused back to him or her during an upcoming surgery.
Directed donors donate blood to be transfused
to a specific patient. Directed donors can give whole blood,
two units of red blood cells or apheresis platelets.
Replacement donors give blood to replace the
blood used by a patient-a particularly special way for family
and friends to show their love and support. Replacement donors
play a key role in replenishing the blood supply for the next
patient in need of a transfusion.
Apheresis donors donate blood platelets. The
safe, simple 90-minute process involves separating platelets
from the blood using a blood cell separator.
